Add page-specific Report Issue functionality

JavaScript dynamically updates the Report Issue footer link to include:
- Current page URL (pre-filled in issue body)
- Page title (pre-filled in issue title as "[Docs] Page Title")
- Documentation label automatically applied

This makes it much easier to report documentation issues since users
don't need to manually copy/paste the page URL.
